B FRANK LEEDS, OF BOSTON, MASSACHUSETTS.

COMBINED SNOW SCRAPER AND COMPRESSOR.

EiPECIFICATION forming part of Letters Patent No. 323.433, dated August 4, 1885.

Application filed October-11,1884.

To all whom it may concern:

Be it known that I, B. FRANK LEEDS, 1 citi' zen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented new and useful Improvements in a Combined Snow Scraper and Conn pressor, of which the following is a specifica' tion.

My invention relates to apparatus for pre venting the blocking of and obtaining a uniform and solid surface on city streets or other roadways.

Referring to the drawings, illustrating the mechanism by which I attain these objects and accompanying this specification, Figure 1 is an isometric plan showing a sled, A B 0 D, with a body of proper strength and size adapted to the proposed work, having either solid or skeleton sides, and in either case with an opening or blank space,E F G H,of at least three-fourths the width of the side; a scraper, I J', about three inches less in width than said blank space,and shed with iron,attached at the end K to one sled-runner, and passing thence diagonally across the sled-bod y through and beyond the side containing said blank space about four inches,at a distance of about lour and one-quarter inches above the plane of the bottom of the sled-runners; a compressor, L )I, to be presently described.

Fig. 2 is a plan showing the sled, as seen from above, and also showing, by the dotted line N 0, from where the vertical section shown in Fig. 3 is taken. The other dotted lines indicate the relative positions of the scraper I J and compressor L M.

Fig. 3 is a vertical section through the line N O of Fig. 2, showing a section, I J, of the scraper I J of Fig. 1, and showing also ascc tion, L- M, of the compressor L M of Fig. 1. Said compressor may be constructed eitherin blocks or otherwise, the details of its con struction being easily arrangedand should occupy about one-third of the length of the sled and the entire width of the sled, its first eighteen inches or two feet from the rear of the sled being level, and about one and onehalf inch above the plane of the bottom of the runners, between the points T U, and thence inclining upward about one inch to the foot to the face V of the compressor.

(No model.)

Fig. 4: shows a section of a metallic removable extension, W', (omit-ted from Fig. 1 for clearness,)of the scraper I J of Fig. l, to an end of which in section it is shown affixed by the bolts 1 and 2. This extension is intended for use by increasing the width of the scraper when it is desired to reduce the amount of snow passing beneath the compressor.

In the drawings,the scraper is shown so arranged as to deliver the surplus snow through the opening or blank space on the left side of the sled in order to bring the runner next the sidewalk on the right hand, where the driver naturally sits; but I do not confine myself to such arrangement, which may be reversed.

The operation of my invention is as follows: The sled is to be driven with its closed side, meaning by this the side not containing the blank space E F G H of Fig. 1,near the curb stone or sidewalk. The tendency of the continuous force of the snow upon the scraper will be to force the sled laterally against the curb, and a strap-buffer may be used to protect the right runner from direct collision therewith. A portion of the snow will be caught by the scraper and carried through the blank space into the center of the street. Another portion will pass beueath the scraper, and thence under the compressor, and being gradually compressed by the hopper-shaped space formed or inclosed by the compressor and the surface beneath, will be by this means diminished about one-third in volume, or in proportion to the weight upon and included within the compressor, which weight may be easily varied, as desired. A repetition of this operation on the opposite side of the street or roadway will result in the formation of a hard road-bed,except in the center part of the street where loose snow will be left, which may be compressed either by use of the compressor alone or by the method and apparatus shown by me in volume 32, page 20, of the Scientific American for January 9, 1875. If the compressor is to be used, then the scraper should be hinged to the under side of the door of the sled.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A sled provided with a blank space in one of its sides, and a scraper, as described,

pressor, the combination of the blank space E 10 F G H, scraper I J, and extension Wwith the compressor L M, substantially as and for the purposes described, as set forth.
